I wasn't able to find much information but it looks like Dragon Naturally Speaking has COM interface, which is good news.Here, and here are two examples of using this interface with AutoHotkey. The second examle has the more recent syntax, you don't want to use the 'COM Standard Library' mentioned.

I use Dragon Naturally Speaking with ahk, so I use voice my commands to run the scripts. But I've never had DNS actually "speak" to me... do you mean have DNS read out loud a passage of text, for example? If so, there are other options as well to do this. Maybe if you clarify what you want to do I could give you a bit more info

Listener:=ComObjCreate("Dragon.DgnVCmd.1"); create Dragon's command objectListener.Register("",1); register itListener.ExecuteScript("TTSPlayString ""This is a test. Did it work?"", """"",0); ececute the command TTSPlayString. See Dragon help for details. Watch out for the double quotes in the string!Sleep,10000; or do something else...Listener.Unregister(); unregister your object when you don't need it anymore

In theory you should also be able to use the DgnVoiceTxt or VTxtAuto COM-interfaces directly, but at least on my machine they're not registered by default, so the above is probably the safest way to do it.

Btw: the EmulateRecognition in your original post does not speak a text but simulates the recognition of a text. The corresponding command for Dragon would be the function RecognitionMimic("text") in the Dragon.DgnEngineControl object.

That's actually, exactly what I wanted was the equivalent of said script.
